According to the Tomshardware portal, this is the first fully flexible resistive RAM device. Its main components are droplets of liquid gallium metal (the charge used for 1/0 values of binary memory). Each “drop” is squeezed into a type of container made of stretchable Ecoflex biopolymer.
Each blob can store 8 bytes of memory, which is less than current DRAM devices, but the key difference with FlexRAM is the ability to retain information for 12 hours after the device is powered off.
At the same time, liquid metal RAM has a limit of 3500 rewrite cycles. Although experts are not enthusiastic about the capabilities of the new product, they still see potential in this invention for robotics and future developments. The fact of creating such a device is promising.
As Jing Liu, one of the Tsinghua University researchers working on FlexRAM, puts it, this development offers “a theoretical basis and a technical pathway for future soft intelligent robots, brain-machine interface systems, and wearable/implantable electronic devices.”
